Comparison of pepsinogen forms in cattle, sheep and goats
(1990)
Different types and subtypes of pepsinogen extracted from bovine, ovine and caprine abomasa were found to differ according to their phosphate content and relative molecular mass (Mr). Bovine pepsinogens had organic phosphate ...
From educational philosophy to educational practice: fidelity and the curriculum in context
(1990)
As part of a higher degree on research methods, exploratory work was undertaken concerning educational philosophy and educational practice using an ethnographic approach. This author discusses, using this exploratory work, ...
Optical and infrared polarimetry and photometry of blazars
(1990)
We have carried out a polarization study of 44 blazars and candidate blazars at optical and near-infrared frequencies covering the period 1986 August to 1988 February. The data show flux and polarization properties changing ...
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 2 : the wavelength dependence of polarization
(1990)
We discuss the wavelength dependence (0.44-2.2 micron) of polarization of the sample of 71 Seyfert and three broad-line radio galaxies presented in Paper I. For four galaxies, 3A 0557-353, Fairall 51, IC 4329A and NGC 3753, ...
The effect of (-)-hydroxycitrate on the activity of the low-density-lipoprotein receptor and 3-hydroxy-3-methylglutaryl-CoA reductase levels in the human hepatoma cell line Hep G2
(1990)
(-)-Hydroxycitrate, a potent inhibitor of ATP citrate-lyase, was tested in Hep G2 cells for effects on cholesterol homoeostasis. After 2.5 h and 18 h incubations with (-)-hydroxycitrate at concentrations of 0.5 mM or higher, ...
Pepsinogen types in worm-free sheep and in sheep infected with Ostertagia circumcincta and Haemonchus contortus
(1990)
Pepsinogen isolated from the plasma of Dorset wethers with abomasal burdens of Ostertagia circumcincta was found to have the same proportions of three zymogen subtypes as that isolated from the plasma of Merino wethers ...
